SJM has contacted a civil engineer for the plan of <br />operations concerning sediment control, a water management plan, a road stabilization <br />plan, and a river crossing plan, for expertise in acceptable procedures for this application. <br />An onsite visit will be required for an accurate site evaluation to be performed. Due to <br />the amount of snow fall present in the area, it is expected that this could take 30 to 60 <br />days to accomplish. As soon as the site is accessible, SJM will be visiting the site with <br />the civil engineer to perform the necessary evaluations, as well as staking the river <br />crossing location, path to the mine site from Forest Service Rd. 250, the pit location, <br />stockpile locations, and mine site boundaries. At the time the site is considered <br />accessible, SJM will contact all personnel addressed in this letter in advance to extend an <br />invitation to be present to conduct your individual analysis as we will be present at the <br />site. Reclamation cost of the river crossing will be determined after the site evaluations <br />have been completed. <br />There will be NO discharge of waste water into the Alamosa River. Groundwater <br />exposed during excavation will be used for the processing equipment and returned to the <br />pit. As the vegetation is removed and stockpiled, a slope around the pit, deposit stockpile <br />location and waste rock pile location (the screened material greater than '/2 ") will be <br />graded to drain all water and sediment created or exposed towards the pit. This is not <br />expected to increase disturbance or change reclamation cost as removing the vegetation <br />layer has already been calculated. The nozzle on the water pump will be kept near the <br />surface of the water in the pit at the opposite end of discharge to allow sediment to settle <br />within the pit and water to be reused during operation. The deposit material ejected from <br />the vibratory screener consisting of I /z" or larger waste material will be returned to the pit <br />upon completion of processing all deposit material stockpiled. This will allow an <br />adequate amount of exposed groundwater to be continually reused during the processing <br />of deposit material without the need for discharge into the Alamosa River. All water <br />exposed and used will be returned to its place or origin with the exception of water lost <br />due to evaporation, which is considered to be minimal. The vegetation stockpile will <br />have a silt fence constructed with 2 foot wooden stakes and retention fabric around it to <br />control sediment runoff in the event that it rains. SJM does not believe that this will <br />
